Pickwick is a British television musical made by the BBC in 1969 and based on the 1963 stage musical Pickwick, which in turn was based on the 1837 novel The Pickwick Papers written by Charles Dickens. It stars Harry Secombe as Samuel Pickwick and Roy Castle as Sam Weller.

Sam Weller is a fictional character in The Pickwick Papers (1836), the first novel by Charles Dickens, and the character that made Dickens famous. A humorous Cockney bootblack, Sam Weller first appeared in the fourth serialised episode. Previously the monthly parts of the book had been doing badly, selling only about 1,000 copies a month — but the humour of the character transformed the book into a publishing phenomenon, raising the sales by late autumn of 1837 to 40,000 a month.
